SETaF-LUBRICATING. SPINDLE AND WHARVE FO'R SP I NNING SPZNDLES.

Application filed December 29, 1921. Serial No. 525,722.

To all whom it may concern:

Be it known that I, KEITH STEWART, manager Auckland Jute Mill,Shamnaggar, Bengal, British India, subject of His Majesty the King ofEngland, residing at Auckland Jute Mill, Shamnaggar, have inventedcertain new and useful Improvements in Self-Lubricating Spindles andWharves for Spinning Spindles, of which the following is aspecification. I

My invention relates to an improved construction of spindles of the typein use in spinning frames for jute, flax, cotton Worsted and the likeand has for its object to provide a spindle attached to ball bearingsand having the bearings and the spindle within constant bath of oil.

A further object of the invention is the construction of the Wharvewherein the Wharve is constructed with a cavity to act as an Ollreservoir and the ball bearings are aflixed to the centre-thereof toprevent any transverse strain on the wharve or pulley.

The spindle passes through a stationary metal socket set within the neckrail, and said stationary socket is securely attached to the neck railby means of a screw or the like. The stationary metal socket iscontinued beyond the neck rail with a reduced sectional area and acts asa brush for the spindle. Ports formed in this part allows of thelubrication of the spindle.

A ball bearing is attached to the lower extreme end of the stationarymember and,

has its outer rotating surface attached to the wharve or pulley.

The Wharve or pulley is made elements, the upper element which is firstpassed over the reduced and continued portion of the stationary membercomprises a hollow ring to form a wharve or pulley. having two annularflanges on its outer circumference to act as guides for thesdrive, andan annular inner flange to form the head of the oil reservoir, oil holesbeing formed in the annular inner flange to allow for lubrications. Alug may be formed in the inner periphery to act as a guide for thefixing of the ball bearings.

The lower end of the upper element is threaded to carry the cap or otherelement of the wharve or pulley. a

The cap is firmly aflixed on to the end of the spindle and has its outercircumference threaded so as to be firmly attached to the of two 1 lowerand inner circumference of element.

'My invention is illustrated in the accompanying drawings in whichFigure 1 shows a sectional elevation of my spindle and w'iiarve, andFigure 2 a side elevation of the neck rail and attachment.

The stationary metal socket 2 passes through the neck rail 3 of aspinning machine and is further held firmly in position by means of ascrew of the like, 4.

the first The metal socket 2 is continued beyond the neck rail 3 with areduced sectional area 5 forming a shoulder 6 right round the socket,the shoulder being flush with the lower surface 7 of the neck rail. Themetal socket at 5 also acts as a bush for the spindle 1. At the lowerand outer edge of the metal socket 2 is affixed the ball bearing 8 whichmakes for the smooth running of the device with a minimum of power.

The spindle 1 passes through the stationany metal socket 2 with aclearance of about 3 2- The spindle has a series of spiral grooves 9 cuton its outer periphery to allow for the constant lubrication of thespindle when same is being worked. The spiral grooves gradually shallowtowards the upper end of the socket and by means of these grooves thespindle 1 working Within the metal socket 2 is covered with a thin filmof oil.

The wharve or pulley is made of two parts, the hollow casing 10 havingan annular flange 11 on its upper and inner surface to form the cover ofthe oil reservoir. A hole (or slots) 12 are formed under the flange 11to allow the lubrication of the device. The outer surface of the casing10 hasi'annular flanges on its extreme edges to act as guides for thedriving means.

The wharve 10 is first passed over the end 5 of the stationary metalsocket 2 and the ball bearings 8 are then inserted between thestationary metal socket and the casing. The inner surface 13 of thebearing being attached to the stationary socket 2 and the outer rotatingsurface 14 of the bearing fixed to the inner circumference of the casing10. An amiular shoulder 15 may be formed in the imier face of the casing10 to act as a guide to position the bearing 8.

The bearing 8 being positioned at the centre of the wharve 10 the pullis directed on it and the spindle is thereby not subjected to anytransverse strains.

lhe cap 16 of the wharve or pulley rigidly attached to the end of thespindle 1 and is screwed into, or otherwise secured to the innerperiphery of the lower end of the casing 10 as at 17.

The hollow outer casing 10 and the cap 16 thus form an oil reservoir inwhich the ball bearings work and ports are formed in the metal socket at18 to allow of the access of oil to the spindle. Owing to the rotatingmotion of the wharve the oil under centrifugal action rises along thesides of the wharve and thus gains access to the spindle by means of theports 18.

I claim:

1. A combined pulley and spindle, com prising a fixed socket, a spindlereceived by the socket and a pulley, fixed to the spindle and rotatablyconnected to the socket.

2*. A device according to claim 1, the

pulley being connected to the socket by a single ball bearing, locatedcentrally of the ends of the pulley.

3. A device according to claim 1, the pulley forming a cup for receivinglubricant.

A device according to claim 1, the spindle having a spiral groove on thesurace of the portion received by the socket, the socket beingtransversely perforated, intermediate itsends.

5.21 device according to claim 1, the pulley forming a cup-likereceptacle for receiving lubricant, and the spindle having a spiralgroove on the surface of the portion received by the socket the sockethaving transverse perforations intermediate its ends for coniniunimitingwith the cuplike receptacle, and the spiral groove.

In testimony whereof I aflix my signature.

KEITH STEWART.
